Subject: linux/printk.h: use DYNAMIC_DEBUG_BRANCH in pr_debug_ratelimited
X-Git-Tag: v5.1-rc1~118^2~66
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a9d4ab7a91165f325060d6441169ebeab08a2fec;p=users%2Fjedix%2Flinux-maple.git

linux/printk.h: use DYNAMIC_DEBUG_BRANCH in pr_debug_ratelimited

pr_debug_ratelimited tests the dynamic debug descriptor the
old-fashioned way, and doesn't utilize the static key/jump label
implementation when CONFIG_JUMP_LABEL is set.  Use the
DYNAMIC_DEBUG_BRANCH which is defined appropriately.
